How to castle on Chesscube:- With all the above rules observered, simply move the king 2 squares to the right or left, Chesscube will do the rest.

Note 960 variant:- same rules of castling apply, but to castle move the King on top of the rook as if you were capturing it

This is actually werid because, I took ages to figure out how to castle, when after trying to figure it out for years, I actually did it by accident on my own Lol i know worst story ever narrated in history!

I no good in chess, only practice gets you playing a bit more decent than you where before, so practice and it will work
